Re: Unable to download files from my UbuntuOne account

That doesn't sound very encouraging! You could try filing a bug on Launchpad, or you could try askubuntu (there's a link to it in "other support" at the top of the page. Apart from that, I don't know what to suggest.

Please, people, remember to BACKUP before you install that new system. Same if you're upgrading.

Re: Unable to download files from my UbuntuOne account

I have the same problem described from OP. Some files in some folders are missing in local; via browser i can see it, but when i try to download it appears the message "could not download content from storage". I'm on Ubuntu 13.04.
